I made this stuff for my studio and decided I would like to move on from it and invest in more lab equipment like a nice RLC meter, a Hickok tube tester, or maybe a CNC machine.

Asking $1200 $1,100 $1,000 for the built unit or trades for anything I think is cool and of equal value.Asking $10 per unpopulated audio card ( 6 available4 available ) SoldCan make more PCB's if NYD approves

- MILA Stands for Mic Instrument Line Amplifier- Audio cards designed by me- This is a transformer balanced 2 channel mic preamp with a range switch that changes the gain in approximately 6dBu steps. - Input transformers are Sowter 9610f - Output transformers are Edcor WSM series- Power Transformer is XPWR 050-120 ( 120VAC input )- DI on both channels bypasses mic signal - The power supply used is not the one from the MILA-1 schematic, it's my own traditional style RCRCRC design with 100uF 450VDC Nichicon capacitors - Pad resistors are for a 20dBu input pad- Phase switch was added at the input - 783 style phantom power was added - AC heater wiring is done off of the PCB with artificial center tap added - Tubes are all NOS RCA silvertop 12AV7- Non polarized caps used on audio cards are either WIMA, NOS Mallory, or Cornell Dubilier - Polarized caps on audio cards are Nichicon- Resistors are all low tolerance metal film types - Frequency response is flat from 20 Hz to 20 kHz- Fuse after IEC Inlet- 3u Parmetal Case- Neutric XLR jacks - 0.4% THD + N on each channel when driving a -37dBu signal up to +4dBu- Mostly shielded wiring for audio signals

Noise levels are pushed into checkmate.Works great, sounds huge, and priced to move.
